I'm using myth v0.20 with a nvidia FX5200 video card and Athon XP 2800.  When I
enable XvMC (Standard XvMC) any HD show will playback fine but SD shows stutter.
When playing a SD show the frontend log shows:

2006-09-21 22:56:33.305 NVP: Waiting for prebuffer.. 0 ADADDLAL
2006-09-21 22:56:33.340 NVP: prebuffering pause

2006-09-21 22:56:33.373 NVP: Waiting for prebuffer.. 0 AADAAdLL
2006-09-21 22:56:33.406 NVP: prebuffering pause
2006-09-21 22:56:33.407 NVP: Waiting for prebuffer.. 0 LADAAADL
2006-09-21 22:56:33.440 NVP: prebuffering pause

I've tried all the suggestions from the XvMC wiki "Prebuffering Pause or stutter
with Nvidia" section.

I don't neeed XvMC for playing back SD shows, it is just a pain to have to turn
it on/off as I go back and forth between SD and HD recordings. Is there a way I
can configure myth to only use XvMC for HD shows?
